A DRV B FODRV C MV D IV E PICV 4. In the example of proportional balancing, how many times would valve B be adjusted? A Each time a floor is put into proportional balance (so four times for this four-floor building) B It always needs closing a little at the start of the procedure to allow it to be opened up again to balance used to validate your CPD records.
